Distributing and drilling device for carbon fiber composite material

Abstract

The invention relates to a distributing and drilling device for a carbon fiber composite material and belongs to the technical field of carbon fiber section bar processing auxiliary equipment. The distributing and drilling device comprises a diving board, wherein a drill bit positioning hole is formed in the diving board; the two ends of the diving board are provided with connecting ends; and connecting end positioning holes are formed in the connecting ends. According to the technical scheme, before blank drilling, the diving board is utilized to position a to-be-processed hole of blank, and then, the drilling operation of a drill bit is restrained by use of the drill bit positioning hole, so that the drilling efficiency is improved, and the beneficial effects are remarkable; during practical use, the diameterof the drill bit positioning hole is smaller than that of the to-be-processed hole, the small hole is firstly processed and then the to-be-processed hole is processed, so that the carbon fiber material at the edge of the hole can be effectively prevented from being disintegrated, and therefore, the product qualified rate is increased, the production cost is controlled, and the market prospect is wide.

Description

technical field [0001] The invention relates to a drilling device, in particular to a step-by-step drilling device for carbon fiber blanks, and belongs to the technical field of auxiliary equipment for processing carbon fiber profiles. Background technique [0002] As an advanced composite material, carbon fiber composite material has a series of advantages such as light weight, high modulus, high specific strength, low thermal expansion coefficient, high temperature resistance, thermal shock resistance, corrosion resistance, and good vibration absorption. , strategic weapons (missiles, etc.) and other fields have been widely used. Carbon fiber composite material is a heterogeneous material composed of a reinforcing base and a matrix, and its physical and mechanical properties are very different from homogeneous materials such as metal materials. [0003] Therefore, the cutting process of carbon fiber composite materials is not only affected by the properties of the matrix ...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the cutting process of carbon fiber composite materials is not only affected by the properties of the matrix and reinforcing matrix materials, but also affected by factors such as the orientation distribution of the reinforcing matrix. The cutting process is complicated, and the cutting damage form is very different from that of metal materials. Advanced processing tools and cutting technology will cause a series of problems such as rapid tool wear, drilling layering, etc.

[0004] At present, in the carbon fiber production process, it is necessary to perform cutting operations on the hot-pressed carbon fiber profiles to obtain products that meet the requirements. Since the carbon fiber profiles are made of multi-layer coils, it is easy to cause holes near the processing holes during the drilling process. Material collapse leads to product scrapping, resulting in a low product qualification rate. Due to the high unit price of carbon fiber materials, a high scrapping rate also means higher production costs
